# One-step equations with multiplication and division

This equation can be simplified through a single step to solve for the variable. Can you help?

# One-step equations with multiplication and division

Let's ease into this, shall we? Here's an introduction to basic algebraic equations of the form ax=b. Remember that you can check to see if you have the right answer by substituting it for the variable!

# One-step equations with multiplication and division

Remember that what you do to one side, you have to do to the other. Will you multiply or divide both sides to dump the fraction, x/a? Let's do it together.

# One-step equations with multiplication and division

Let's get a conceptual understanding of why one needs to divide both sides of an equation to solve for a variable.
